An integer is a whole number, -2/15 is not whole. It is real and rational.
Answer:
multiply both sides by 3x + 7
Step-by-step explanation:
this will eliminate the fraction in the equation and therefore make it easier to isolate x
hope this helps :)
Step 1. Factor out the common term 2
n - 2 = 2(5n + 2)/2
Step 2. Cancel 2
n - 2 = 5n + 2
Step 3. Subtract n from both sides
-2 = 5n + 2 - n
Step 4. Simplify 5n + 2 - n to 4n + 2
-2 = 4n + 2
Step 5. Subtract 2 from both sides
-2 - 2 = 4n
Step 6. Simplify -2 - 2 to -4
-4 = 4n
Step 7. Divide both sides by 4
-1 = n
Step 8. Switch sides
n = -1
